Abstract (en)
[origin: US6033043A] PCT No. PCT/JP96/03758 Sec. 371 Date Jul. 14, 1997 Sec. 102(e) Date Jul. 14, 1997 PCT Filed Dec. 24, 1996 PCT Pub. No. WO97/24250 PCT Pub. Date Jul. 10, 1997This invention is to suppress repeated striking noises as generated by a crawler belt (29) when taken up onto a drive sprocket (25) in a polygonally bent shape. A crawler belt support block (34) is fixedly mounted on top of an upper reinforcing plate (19) of a bracket (15) on the side of the drive sprocket. The crawler belt support block (34) includes a skid block (36) with a crawler belt sliding surface (36B) to be held in sliding contact with lower surfaces of respective links (30) of the crawler belt (29) to guide same in a direction tangential of the drive sprocket (25) when the crawler belt (29) is taken up onto the drive sprocket (25). The crawler belt support block suppresses vertical movements as would occur to the crawler belt (29) when taken up onto the drive sprocket (25) in a polygonally bent shape, to reduce the repeated striking noises generated by meshing engagement of bushes (32) of the crawler belt (29) and the drive sprocket (25).
